Poster: A 60 GHz phased array system evaluation based on a 5-bit phase shifter in CMOS technology

This paper explores a 60 GHz phased array system for ultra-high data rate communication in indoor environments. The channel modeling is addressed and the system link budget is calculated. A 16-element phased array system specifications are presented. This paper also presents the design of one of the key blocks - a 5-bit digitally controlled passive phase shifter. The switch-type phase shifter is implemented in 40 nm CMOS technology, with the maximum phase error of 4.68
^°
and the rms gain error of 1.72 dB.
